Re: [Haskell-cafe] haskell crypto is reaaaaaaaaaally slow

aeyakovenko:

$ time ./md5sum ./md5sum [105,252,52,138,187,192,216,17,225,123,185,3,124,101,86,132]

real 0m4.790s user 0m3.688s sys 0m0.492s

$ time md5sum ./md5sum 69fc348abbc0d811e17bb9037c655684 ./md5sum

real 0m0.023s user 0m0.000s sys 0m0.008s

this is my implementation using crypto (http://www.haskell.org/crypto/). Am I doing something wrong?

module Main where

import System import qualified Data.Digest.MD5 as MD5 import qualified Data.ByteString as BS

main = do args <- getArgs dt <- BS.readFile $ head args putStrLn $ show $ MD5.hash . BS.unpack $ dt ^^^^ ^^^^^^^^^

not a good idea. You need an MD5 over bytestrings, not [Word8]. -- Don
